IAC valve 940

Post by Volvo940Stv » Wed Feb 12, 2020 4:28 am

Now I wonder. Is that IAC valve supposed to be stuck sometimes and then it works? If I try to pry with a screwdriver on that throttle. It’s stuck. The width or the opening? Is that supposed to be like that? Idle is still rough. Tried it with two cables on a booster. It opened. But did not close itself. But prying the throttle helped it to return. I tried another IAC with the same opening but it did help a little bit, but the idle is rough. What about bad ECU?

Whole engine has new gaskets. No vacuum leak.
